Experimental/Theoretical Materials Science

Materials science has seen rapid development in the last decade. Superconductors, nanostructures, and self-assembly systems, for example, are several of the many fruits of research into this field. Our research focuses on one aspect of materials science, specifically solid-state materials with novel physical, chemical, or biological properties. Our scientific endeavor consists of both experimental and theoretical work. In the experimental portion of our research, we look for and analyze potentially magnetic or superconducting materials using solid-state chemical techniques. We are interested, among other things, in how the electronic structures of solids can affect their chemical bonding behavior, and how that bonding behavior will determine their physical properties. Tools we use in this research include high-temperature synthesis, powder and single crystal X-ray diffraction, and measurements of physical properties.

In the theoretical part of our research, we analyze the electronic structure of solids, simulate the chemical reaction process in the solid state, and compare the results of our theoretical models with experimental observations. Through the interplay of experimentation and theoretical analysis, we hope to find better ways of making solid state materials with desired chemical and physical properties.

Our theoretical component also includes computer modeling and simulation of biological systems. We try to understand how structures and dynamics can affect the biological functions and behaviors of proteins and lipids. Heme proteins are currently our main interest in this research, and the primary tool we use is a high-speed computer equipped with powerful interactive graphics.

We are also interested in electron and proton transfer processes in biological systems. Computer simulation of these transfer processes requires more sophisticated theoretical techniques because of the quantum nature of electrons and protons. The Feynman path integral method is usually used. Using a fast computer to arrive at numerical solutions of the quantum mechanical equation, we can study how electron and proton transfer processes are affected by the protein environment.
